Abstract
Disclosed is an automatic control system of an air conditioner of a clean operating room in a hospital. The automatic control system mainly solves the problems in the prior art that system manufacturing cost is high, safety performance and network upgrading. The automatic control system comprises three parts which are respectively two industrial personal computers, programmable logic controller (PLC) controllers and operating room operation panels. The industrial personal computers are connected with the PLC controllers through an Ethernet switch. The PLC controllers are connected with the operating room operation panels in an RS485 mode. Control modes of a one-grade and a two-grade operating room purification unit adopt RS485 communication so as to achieve one unit of PLC controller is corresponding to one operating room operation panel. The control modes of a third-grade and a fourth-grade operating room purification unit adopt the RS485 communication so as to achieve one unit of PLC controller is corresponding to three operating room operation panels. Other unit of PLC controller is used for controlling fresh air and a corridor air conditioner unit respectively. According to the automatic control system, cost of the PLC controllers is saved, and system maintenance is simple and convenient.
Description
Technical field
The present invention relates to a kind of automatic control system of clean operating room in hospital air-conditioning, belong to computer application and technical field of automation.
Background technology
The automatic control system of existing clean operating room in hospital air-conditioning, current employing be an industrial computer (host computer), be connected with the PLC in each air-conditioner set controller by ProfiBus DP (situ industrial distributed bus), then adopt the control panel in each operating room and PLC carry out 1 to 1 RS485 mode carry out communication, humiture collection.Namely each indoor control panel needs a corresponding PLC, makes the composition cost of system high like this, and is unfavorable for that the security performance of industrial computer is poor from now on to the upgrading of Internet of Things direction.
Summary of the invention
The present invention is for the purpose of solving the problem, and mainly solves the system cost that prior art exists higher, problem anxious to be resolved in security performance and network upgrade.
For achieving the above object, the present invention adopts following technical proposals: a kind of automatic control system of clean operating room in hospital air-conditioning, and this system comprises two industrial computers, PLC and operating room guidance panel three parts.Described industrial computer is connected by Ethernet switch with between PLC, and PLC is connected by RS485 mode with operating room guidance panel.Control mode for 1,2 grade of operating room purification unit adopts RS485 communication to realize 1 machine set PLC controller to 1 operating room guidance panel.For the control mode of 3,4 grades of operating room purification units, RS485 communication is adopted to realize 1 machine set PLC controller to 3 operating room guidance panels.Its other 1 machine set PLC controller is used to control new wind and corridor air-conditioner set respectively.During in above-mentioned two industrial computers one work, another is for subsequent use.
Feature of the present invention and beneficial effect: due to the reliability adopting industrial computer to improve system significantly, the demand of Internet of Things direction upgrading can be met again.For the control mode of 3,4 grades of operating room purification units in control system of the present invention, adopt RS485 communication to realize 1 machine set PLC controller and control 3 operating room guidance panels, the cost of PLC can be saved, also make system maintenance become easy, dependable performance.

Detailed description of the invention
Embodiment
With reference to Fig. 1, a kind of automatic control system of clean operating room in hospital air-conditioning, this system comprises two industrial computers, PLC and operating room guidance panel three parts.Described industrial computer is connected by Ethernet switch with between PLC, and PLC is connected by RS485 mode with operating room guidance panel.Control mode for 1,2 grade of operating room purification unit adopts RS485 communication to realize 1 machine set PLC controller to the control of 1 operating room guidance panel.For the control mode of 3,4 grades of operating room purification units, then adopt RS485 communication to realize 1 machine set PLC controller and operation cell operating face plate A, operating room guidance panel B and operating room guidance panel C are controlled.Its other 1 machine set PLC controller is used to control new wind and corridor air-conditioner set respectively.During in above-mentioned two industrial computers one work, another is for subsequent use.
With reference to Fig. 2, for the control flow of 3,4 grades of operating room purification units in control system of the present invention:
Start from power on, then carry out initiation parameter, judge that the break period 1 is to no, then calls operating room guidance panel A reading and writing data subprogram, then returns.Judge that the break period 2 is to no, then calls operating room guidance panel B reading and writing data subprogram, then returns again.Judge that break period 3 is to no, then calls operating room guidance panel C reading and writing data subprogram again, and return main program and carry out Data Update, data operation, then call PID and regulate subprogram, then return main program I/O register refress program scanning and terminate to return.
Above-mentioned PID regulates subprogram, is to compare with detection operating room guidance panel measured value for setting warm and humid angle value, and regulation output, exports to control valve signal in system.
Industrial computer preferably grinds magnificent industrial computer, PLC adopts the S7200 series of products of Siemens Company, single-chip microcomputer product with RS485 communication interface, Temperature Humidity Sensor selected by operating room guidance panel.
